I was just wondering if those who has taken the NAPLEX also learned the Jelliffe formula to calculate GFR. I will go over this, but from what i thought, we usually use the Cgroft formula for calculating CrCl. Also, in the RX prep math section, there were no Young's Rule, Clark's Rule, and Child Dosing base on BSA. Can anyone elaborate of these for me...I am using ProntoPass math cards and RX prep to assist in my calculations. Thank you
